Prophylactic Flexible Bronchoscopy Immediately following Open Airway Reconstruction in Children

Abstract

Objectives: Prophylactic flexible bronchoscopy immediately following open airway reconstruction allows for directed clearance of the distal airways, potentially reducing the rate of certain postoperative respiratory complications. In this investigation, we sought to determine if prophylactic flexible bronchoscopy at the conclusion of pediatric open airway reconstruction has any benefit over blind flexible suctioning of the trachea. Methods: A retrospective, single-center study at an urban tertiary care hospital was completed. From January 2010 to April 2013, patients underwent open airway reconstruction, immediately followed by blind flexible suctioning of the trachea for distal airway clearance. From May 2013 through December 2016, sequential patients underwent prophylactic flexible bronchoscopy immediately following airway reconstruction. Results: A total of 29 patients (age: 3.6 months-6.2 years) met inclusion criteria. Sixteen sequential patients underwent simple blind flexible suctioning and 13 sequential patients underwent directed, prophylactic flexible bronchoscopy. Demographics and comorbidities between the groups were equivalent other than slightly older age in the prophylactic bronchoscopy group. All clinical outcomes analyzed were equivalent other than faster time to room air ( P < .002) and a decrease in the number of chest physical therapy sessions ( P < .02) in a subset of patients who did not undergo prophylactic bronchoscopy. Conclusion: This investigation suggests that the use of prophylactic flexible bronchoscopy immediately following open airway reconstruction may not be superior to blind flexible suctioning of the trachea in limiting postoperative pulmonary complications. Further studies of greater power are needed to better elucidate any small differences that may exist between these two interventions.
